To all whom it may concern:

Be it known that we, JOHN L. WHITE- HURST and CHARLES H. W111), citizensof the United States of America, residing at Baltimore, Maryland, haveinvented certain Improvements in Machines for Casing or Boxing Cans, ofwhich the following 1s a speclfication.

This invention relates to certain improvements in that class of machineswhereby cans automatically stacked therein, are forced therefrom into apacking case or box and in a condition for shipment, as will hereinafterfully appear. I

In the further description of the said 1nvention which follows,reference is made to the accompanying drawings, forming a part hereof,and in which Figure 1 is an exterior side view of the machine, and Fig.2 a plan of certain parts of the same as viewed in the directionindlcated by the arrow in Fig. 1.

Fig. 3 is a sectional side view of the mechanism whereby the cans arepushed from the remaining portion of the machine into a packing case orbox, not shown, together with certain other elements of the machinewhich cooperate with them and which are shown in dotted lines.

Fig. 4 is an enlarged side view of certam details of the machine; andFig. 5 an end view of the same. 0

Fig. 6 is a view of certain parts shown in Fig. 1, illustrating apeculiar movement pf the cans as hereinafter described, and Fig. 7 anenlarged view of parts of Fig. 6.

Referring now to the drawings, 1 is the wheeled frame of the machine,and 2 a receptacle supported by the frame, and shown as formed of angleiron bars 3, into which cans are delivered from an ordinary runway notshown.

The bars 3 are arranged to form three channels a, b and c which are openat the top for the reception of the cans from the runway, and whichserve to distribute the cans into vertical and horizontal rows; and itwill be understood that in the operation of the machine the cans firstenter and fill the spacea, and after that space is filled, the nextspace Z2 receives the cans which roll over the top can in space a, andthis opera tion is continued until all the spaces are filled, when thefurther rolling of the cans on the runway is prevented by the stop d,

cans are discharged.

4 is an angular plate seated on the frame 1, a part of the bottom ofwhich serves as a seat for the packing case or box, not shown, intowhich the cans, twelve in number, are pushed at each operation of themachine; and 5, 5 are fixed horizontal shelves, two in number, whichproject from the vertical portion of the plate 4 and which, togetherwith the horizontal part of the said plate, support the delivered cansin horizontal and vertical rows, as is well shown in Fig. 1 of thedrawings.

7 is a pusher whereby the twelve stacked cans at each operation of themachine, are pushed into the packing box or case, and it is shown asconsisting of the vertical bars 6 and the horizontal bars f, the latterbeing secured to the former by the rods 9.

The pusher at its inner end is supported by the plate 4 through themedium of the rollers 9 which are journaled to lugs on the bottom of thelowest of horizontal bars as shown in Figs. 1 and 3.

The means whereby the pusher is given a forward, and a backwardmovement, the former to carry the cans into the packing case, and thelatter to carry it away from the box, consist of a bell-crank foot lever10 pivoted to the frame 1 at h. The short arm of the bell-crank lever isconnected by a link j to the arm 13 which is hinged at its lower end tothe frame, as shown in Fig. 3.

The upper end of the arm 13 is branched as best shown in Fig. '2, andthe branches are'united by curved-links 2' to the central horizontal barf of the pusher.

The forward or operative movement of the pusher is of course, efiectedby the foot of the operator, while its backward motion,

when the foot lever is released, is produced by the coiled spring 14which connects the foot lever to a part of the frame 1 as shown in Fig.3.

It is necessary before the pusher is moved forward to carry the twelvecans resting on the shelves 5 and the plate 4 to the packing case, thatthe delivery of the cans from the I and not again resumed until thetwelve piled receptacle 2 should be suspended, and the cans in thereceptacle, and those in the runway, forced backward a limited distanceto produce a space between the two sets of cans that is to say the canson the shelves 5 and the plate 4, and those in the channels a, b, and 0and thereby avoid friction between them, and to this end, the followingdescribed mechanism is employed.

Referring now particularly to Fig. 2, 15 is a horizontal straight barattached to one side of the pusher 7 by means of the angle iron is, soas to have a forward and backward movement in common with the pusher,and it is guided and partially supported by the roller 20 on a lug mwhich is a part of the frame 1.

22 is a vertically slidingv plate situated between bar 15 and a fixedangle iron 23 (see Figs. 1, 2 and 4) havin pins 24 which extendhorizontally there rom, adapted, when the plate 22 is in its highestposition as shown in Fig. 4, to project into the path of the cans in thereceptacle 2 and thereby prevent their discharge from the spaces a, band c as shown particularly in Fig. 4.

The said pins also operate to push back the cans in the said receptaclea limited distance, in order that their front verticalrow will not chafethe adjacent four cans carried by the pusher when brought forward ortoward the packing box, as hereinafter described.

By references to Fig. 6 it will be seen that when the pins 24 are intheir lowest position, they are below the cans and therefore admit ofthe cans in the channels pressing against those on the shelves 5, andthe plate 4, as best shown by the full lines, but as the pins 24 risethey strike the cans and push them back, as shown by their dotteddelineation in that figure, for the reason that the pins in their upwardmovement rise to nearly the center of the cans. In other words the pinsin rising not only extend into the path of the cans and prevent theirdischarge, but strike the bodies of the cans and push them back. In Fig.7 the pins 24 are shown as in their highest position; and in"Fig. 6 asin their lowest position in full lines, and in their highest position indotted lines.

The plate 22 is elevated to its highest position shown in Fig. 4, as thebar 15 moves in the direction indicated by the arrow, and by theprojection 29 of the said bar engaging the roller 30, and it is so helduntil in the return of the bar by the pin 32 passing over the notchedend of the spring-held latch 31; and it will be understood that while soheld, the pins 24 prevent the passage of the cans from the channels a. band c of the receptaole, 2 to the shelves 5 and the plate 4.

-From the foregoing, it will be understood that when the plate 22 isallowed to fall from its highest position shown in Fig. 4, the pins 24will not only pass to below the cans in the receptacle 2, but due to theangularity of the slots 27 they will be laterally withdrawn from thecans, and they will therefore offer no obstruction to a second passageof cans to the shelves 5 and the plate 4 from which they will'be carriedforward by thepusher into the packing box upon the pressing down of thefoot lever, as before stated.

In the return or backward movement of the bar 15, the projection 29 atthe 'end of the bar 15 comes in contact with the roller 30 which ispractically a part of the plate 22, and the said plate is slightlyelevated, and the pins 15 strikes the lower portion of the latch 31 andthrows its upper end out of contact with the pin 32 which allows theplate 22 to fall. I

The roller 30 in falling strikes the inclined part 29 of the bar 15 asshown by the dotted lines, and the further fall of the roller and theplate 22 is a gradual one.

It will be understood that a charge of cans forced by the pusher towardthe packing case, will cause a prior charge to be carried into the case,and in consequence, the case, should it hold 24 cans, will be filled intwo operations of the machine. This feature however is not new and isfound in prior patents.

We claim as our invention 1. In a machine for the purpose described, anopen top receptacle to receive cans from a runway, having inclined barswhich separate the cans delivered thereto into horizontal rows, combinedwith means to check the discharge of cans from the receptacle and at thesame time move them backward, and then'release the cans, and a pusher todrive the discharged cans laterally from the machine.

2. In a machinefor the purpose described, an open top receptacle toreceive cans from a runway, provided with inclined bars which separatethe cans delivered thereto into horizontal rows, combined with avertical bar situated at the delivery end of the receptacle havinghorizontally projecting pins, and means whereby the said bar is given acombined vertical and lateral reciprocating movement to prevent thedischarge of the cans and at the same time force them back in thereceptacle and then release them.

3. In a machine for the purpose described, an open top receptacle intowhich cans are delivered from a runway, provided with inclined barswhich separate the cans delivered thereto into horizontal rows, combinedwith a vertical bar situated at the delivery end of the receptaclehaving horizontally projecting pins, means whereby the said bar is givena combined vertical and lateral reciprocating movement, to alternatelyprevent the discharge of the cans and at the same time force them backand then release them, foot-operated devices to push the cans dischargedas described, laterally from the machine, and spring operated mechanismto effect the return of the can-packing devices to their originalposition.
